AbstractA soil erosion model including interrill erosion and rill erosion was developed for hillslope. The rainfall and slope characteristics affecting soil erosion on hillslopes was analyzed by simulation. The results show that the slope length and gradient, rainfall intensity and process have varying influence on runoff and soil erosion. The unit discharge of runoff and erosion rate increases with increases in the rainfall intensity and the slope length. The same precipitation but with different rainfall processes may cause different runoff and erosion results. The effect of the slope gradient on runoff and soil erosion can be both positive and negative. There exists a critical slope gradient for runoff and soil erosion.
